MICHAEL H. DORGAN, OF MAYFIELD, CALIFORNIA.

VEHICLE-WASHER.

Specification of Letters Patent.

Patented Nov. 19, 1907'.

Application filed March 191906- Serial No. 806,698.

To all whom tt may concern:

Be it known that I, MICHAEL H. DoRGAN, a citizen of the United States, residing at Mayfield, Sainta Clara county, State of (lalifornia, have invented certain new and useful Improvements in Vehicle-Iashers and I do hereby declare the following to be a full, clear, and exact description of the saine.

My invention relates to that class of vehicle washers to which, from the fact that the device is pivotally suspended from the ceiling, the term overhead is applied.

The object of my invention is to provide a simple, economical and effective washer of this class; and to this end my invention vconsists in a novel swivel-coupling by which the device is pivotally suspended, and in a novel means for yrelieving said coupling of side strain or twist, and keeping it true and free to turn without cramping under pulling strain laced upon the water branch and hose w iile being used.

Referring to the accompanying drawings, Figure 1 is an .elevation of my vehicle washer. Fig. 2 is a vertical sectionJ enlarged, of the swivel coupling.

1 is the ceiling of the room, through which projects the nipple 2 of a water main. To this nipple is connected the swivel-coupling, best seen in Fig. 2, and composed as follows: 8 is the inner or stationary member, comprising a main body, an inlet neck 4, and an outlet throat 5. The neck joins the body by a slo ing shoulder or up er bearing 6, and the throat oins the body by a corresponding sloping `shoulder or lower bearing 7. The outer or turning member is in two sections, to Wit, the shell 8, and the carrying tee 9. The shell 8 has an annular sloping top flange 10 which bears upon the up er shoulder 6 of the inner member 3, and t e lower end of said shell terminates at the beginning of the lower shoulder 7 and is externally threaded, as shown. The carrying tee 9 has an upper internally threaded flange 11 which screws upon the lower end of the shell, and it also has a sloping seat 12, ywhich bears upon the lower shoulder 7 of the inner member 3. The parts of this swivel-coupling are easily assembled by first slipping the inner member 3 up into the shell 8 and then screwing the tee 9 up to its seat. It will thus be seen that the outer member, comprising the shell 8 and the tee 9, is freely turnable about the inner member and good joints may be formed between the upper and the lower bearings or seats of the two members. Into one of the horizontal arms of the carryingtee 9 is screwed the water branch 13, to the extremity of which is suitably connected the hose 14. The other horizontal arm of the tee 9 is preferably made with a blind or plugged internally threaded socket, and into this is screwed the strain-relievh1g arm 15, which bends upwardly and has fitted toits upper end a roller 16 which bears against the ceiling 1. The descending vertical arm of the tee 9 is likewise best made with a blind'or plugged socket into which is screwed the post 17, of a truss brace 18, the extremities of which are suitably connected, one with the water branch 13 and the other with the strain-relieving arm 15.

It will readily be seen that the roller 16 traveling against the ceiling relieves the swivel-coupling of all side strain or cramping twist due to the weight of the water branch and hose, or to the necessary pulling upon them during use, so that said coupling turns fairly and freely with the minimum' of frictional wear and with the greatest ease.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is 1. In a vehicle washer, a fixed water supply pipe, a fixed bearing adjacent thereto a hollow member swiveled to said supply pipe, a water branch extending from one side of said hollow member, and a rigid strain relieving arm extending from the opposite side of said hollow member and terminating in an up wardly extending bearing portion adapted to contact with the under side of said fixed bearing. l 4

2. In a vehicle washer, a fixed water supply pipe, a fixed bearing adjacent thereto a hollow member swiveled to said supply pipe, a water branch extending from one side of said hollow member, and a rigid strain relieving arm extending from the opposite sido of said hollow member and having a roller traveling against the under side of said fixed bearing.

3. In a vehicle washer, a fixedwater supply pipe depending from a ceiling or fixed support, a hollow member swiveled to said supply pipe, a water branch extending laterally from one side of said hollow member, a rigid strain-relieving arm extending laterally from the opposite side of said hollow member andl terminating in an upwardly extending portion provided with a roller traveling against the under side of said fixed support.

a swivel-coupling suspended from the ceiling and comprising a stationary inner member formed with an inlet neck and an outlet throat each joining the body with a bearing shoulder, an outer revoluble member consisting of a shell Section having a top iange seated directly on the neck shoulder of the inner member, and a. carrying section iitted to the lower end of the shell Section and having a seat bearing on the throat shoulder of the inner member, a water branch fitted to one side of the carrying section, and a rigid strain-relieving arm iitted to the opposite side ofthe carrying section and having aroller traveling against the ceiling to counteract the side strain of the branch on said swivel coupling.

5. In a vehicle washer,

the combination of a suspension Swiveled coupling comprising a stationary inner member formed with an inlet neck and an outlet throat, each joining the body with a slo ing bearing shoulder, and an outer revolub e member consisting of a shell section havin@ an inclined flange seatedvdirectly on the szlo ing neck shoulder of the inner member, an( a carrying section fitted to the lower end of the shell section and having an inclined seat bearing directly on tohe sloping throat shoulder ofthe inner mem- In witness whereof I have hereunto set my hand.

MICHAEL H. DOHGAN.
